Title:
CONSTANT POLARIZATION OPTICAL FIBER
Document Type and Number:
Japanese Patent JPS6199109
Kind Code:
A
Abstract:
PURPOSE: To generate strong stress in the core of an optical fiber to improve constant polarization characteristics by embedding a stress donor made of multicomponent type glass in the quartz type clad in the symmetrical positions with respect to the core located at the center.
CONSTITUTION: The core 1 and the clad 2 are both made of quartz glass and the stress donors 3 made of multicomponent type glass are embedded in the clad 2 in the symmetrical positions with respect to the core 1 centered at the optical fiber.
